I roto i ngā tukanga ahumahi pāmahana teitei, ko te ine tika me te pono i te pāmahana te tūāpapa o te whakahaere kounga hua, te haumaru whakahaere, me te whai huatanga o te pūngao.Ngā ngongo tiaki wera honohono-nitride silicon carbide (NB SiC)he otinga tino pai, e whakamahi ana i ngā painga mahi tahi o te silicon nitride me te silicon carbide hei tino pai i roto i ngā taiao tino uaua. Haunga ā rātou mahi tino pai, mā ā mātou āheinga whakaritenga kua whakaritea ka taea te whakauru pai ki ngā momo ahumahi rerekē, ka waiho hei whiringa pai mā ngā kaihanga o te ao.
Ka horapa ngā whakamahinga o ngā ngongo tiaki thermocouple NB SiC puta noa i ngā ahumahi maha e hiahiatia ana, nā ō rātou āhuatanga tino pai—te pumau i te pāmahana teitei tae atu ki te 1500°C, te ātete pai ki ngā ru wera, me te ātete kaha ki te waikura. I roto i te tukatuka konganuku kore-ferrous, he mea nui ēnei mō te ine pāmahana i roto i ngā oumu rewa konumohe, konutea, parahi, me te konupora. Kāore i rite ki ngā rauemi tuku iho, kāore te NB SiC e whakapoke i ngā konganuku rewa, e whakarite ana i te parakore o ngā hua whakamutunga me te pupuri tonu i te pumau mō te wā roa. Mō te umanga maitai me te konganuku, ka mahi pono ēnei ngongo i roto i ngā oumu pupuhi me ngā tukanga hurihuri wera, me te tu atu ki te pakū mai i te puehu tere-teitei me te scoria.
He nui ngā painga mō ngā rāngai matū me te hinu i tō rātou koretake matū, e ātete ana ki te horo o ngā waikawa kaha, ngā kawakore, me ngā hau paitini i roto i ngā whakapūnga waro me ngā oko tauhohenga. He tino pai hoki tā rātou mahi i roto i ngā tipu me ngā oumu tahu para-ki-te-pūngao, e tu ana i ngā taiao hau paipa pāmahana-tiketike matatini kei roto ko te whanariki me te hauhautanga. Hei tāpiri, i roto i ngā ahumahi uku, karāhe, me te maimoatanga wera, ko te iti o te tauwehenga whānui wera (4.7×10⁻⁶/°C i te 1200°C) ka taea te mahi pumau i roto i ngā huringa whakamahana me te whakamatao tere, e whakarite ana i ngā pānui pāmahana tika.
Ka tukuna e ā mātou ngongo tiaki thermocouple NB SiC he whakaritenga whānui hei whakatutuki i ngā whakaritenga motuhake o te kaupapa. Mō ngā ine, ka whakaratohia e mātou he diameter o waho ngāwari (8mm ki te 50mm) me ngā diameter o roto (8mm ki te 26mm), me ngā roa ka taea te whakarite tae atu ki te 1500mm, neke atu rānei i runga i ngā tuhi. Kei roto i te whakaritenga hanganga he tauira matapo-pito kotahi-wahi hei whakapai ake i te roa me ngā kōwhiringa whakairinga - pērā i ngā miro M12×1.5, M20×1.5 rānei, ngā flange pumau, neke rānei, me ngā hoahoa awaawa - kia uru pai ki ngā taputapu o nāianei.
Ka taea hoki te whakarerekē i te hanganga o ngā rauemi, me te ihirangi SiC mai i te 60% ki te 80% me te ihirangi Si₃N₄ mai i te 20% ki te 40%, e whakataurite ana i te mahi me te utu mō ngā tono waikura, pāmahana rānei. Ka tukuna hoki e mātou ngā maimoatanga mata hei whakaiti i te porosity (ki raro ki te <1% te porosity mata) me te whakapai ake i te ātete waikura, me te takai ritenga mō te kawe tawhiti. Mā te mana whakahaere kounga tino pakari me te tuku tere (kei te wātea te tuku ohorere 48-hāora), ka whakarite mātou i te mahi pumau me te tuku i te wā tika.
Kōwhiria ngā ngongo tiaki thermocouple silicon carbide e honoa ana ki te nitride mō te ine pāmahana pono i roto i ngā taiao uaua. Mā tō mātou tohungatanga whakaritenga ka tino pai te urutau ki ō hiahia ahumahi, ka whakaitihia ngā utu tiaki me te wā kore mahi. Whakapā mai ki a mātou i tēnei rā ki te matapaki i ō whakaritenga me te tiki i tētahi otinga kua whakaritea.
